Can a mesh be used as a guide for hair?
I love curves. To make it look less noodle like, go to the curve circle and edit the shape of it. To give it more of a stand like appearance just copy some of the vertices in the circle detached from the original circle. It turns out beautifully, but don't be afraid to copy a lot of detached vertices. Also, another thing is the curve. That is what makes it thick and thin. I hope this was helpful.
